Claudia Mello-Thoms, PhD
Title/Position
Associate Professor in the Departments of Radiology and Biomedical Engineering
Director, Medical Image Perception Laboratory
Claudia Mello-Thoms received her joint PhD in 2001 from Rutgers University and the University of Medicine and Dentistry of New Jersey. She has worked at the University of Pennsylvania, University of Pittsburgh and University of Sydney in Australia. In 2018, she joined the prestigious Medical Image Perception Laboratory in the Department of Radiology, University of Iowa. Her research interests are visual search, medical image perception, and image understanding. She seeks to understand why errors occur in the reading of radiological or pathological images.
Stephen Hillis, PhD
Title/Position
Research Professor in the Departments of Radiology and Biostatistics
Stephen Hillis has been a Research Professor in the Department of Radiology since 2012. His educational background includes a PhD in statistics and an MFA in music, both from the University of Iowa. He is the author of more than 100 peer-reviewed publications and 4 book chapters. Since 1999 his research has focused on developing statistical methods for analyzing radiologic diagnostic studies that involve human readers. He was introduced to this field in 1999 when he began working with Don Dorfman in the Dept. of Psychology at the University of Iowa.
Emeritus Faculty
Kevin Berbaum, PhD
Title/Position
Professor Emeritus
Kevin Berbaum, now a professor emeritus of Radiology at the University of Iowa, dedicated more than 30 years of his career to the study of satisfaction of search (SOS), the phenomenon where the detection of one lesion impairs detection of others in an image. He studied this extensively, focusing on chest radiographs, chest CTs, abdominal contrast patients, and multi-trauma patients, and his insights into the nature of SOS have defined the field. He also made significant contributions to receiver operating characteristic (ROC) analysis by characterizing "proper" ROC curves and creating — with Donald Dorfman and Charlie Metz — the Dorfman-Berbaum-Metz algorithm for analyzing multi-reader observer performance studies, one of the most utilized methods for carrying out such analysis since its 1992 creation.
Mark Madsen, PhD
Title/Position
Professor Emeritus
Professor Emeritus in the Department of Radiology at The University of Iowa Carver College of Medicine. Dr. Madsen is a medical physicist with over 25 years of experience in medical image processing and image reconstruction. He has extensive experience using Interactive Data Language to create displays of digital images of various types.
Former Faculty
Kevin Schartz, PhD, MCS
Title/Position
Former Research Associate Professor
Kevin Schartz is a former Research Associate Professor in the Department of Radiology at the University of Iowa Roy J. and Lucille A. Carver College of Medicine. His educational background includes a Ph.D. in experimental psychology specializing in psychophysics and a master of computer science (M.C.S.) degree specializing in software engineering. Dr. Schartz worked with Dr. Donald Dorfman and Dr. Kevin Berbaum, beginning in 1998, developing and maintaining the Dorfman, Berbaum, and Metz (DBM) software (RSCORE, CBM, and MRMC). He also worked with Dr. Stephen Hillis to develop the Multi-Reader Sample Size Program for Diagnostic Studies.
